How to end request with 404 in an IHttpModule?
I'm writing a new IHttpModule. I would like to invalidate certain requests with 404 using a BeginRequest event handler. How do I terminate the request and return a 404?
You can explicitly set the status code to 404 like:
HttpContext.Current.Response.StatusCode = 404;
HttpContext.Current.Response.End();
Response will stop executing.
你可以试试
throw new HttpException(404, "File Not Found");
另一种可能性是：
HttpContext.Current.Response.StatusCode = 404;
HttpContext.Current.Response.Flush(); // Sends all currently buffered output to the client.
HttpContext.Current.Response.SuppressContent = true; // Gets or sets a value indicating whether to send HTTP content to the client.
HttpContext.Current.ApplicationInstance.CompleteRequest(); // Causes ASP.NET to bypass all events and filtering in the HTTP pipeline chain of execution and directly execute the EndRequest event.
